Ubuntu 16.04 LTS : OpenStack Keystone vulnerability (USN-3448-1)

high Nessus Plugin ID 103811

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

Boris Bobrov discovered that OpenStack Keystone incorrectly handled federation mapping when there are rules in which group-based assignments are not used. A remote authenticated user may receive all the roles assigned to a project regardless of the federation mapping, contrary to expectations.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected keystone and / or python-keystone packages.
